My research focuses on physical processes of star formation and the interstellar medium (ISM). The ISM is highly dissipative so that stars would form very rapidly unless energy is continuously replenished. Since stars themselves are the major source of energy, star formation is self-regulated by its own feedback, which drives turbulence and heats the ISM. Star formation feedback also launches galactic outflows, and eventually controls formation and evolution of galaxies. Knowledge about the ISM and star formation rates (SFRs) in galaxies is thus crucial to understanding evolution of galaxies and the universe. As a theoretical astronomer, I am pursuing a theoretical/numerical study to develop a comprehensive theory of the ISM and SFRs. At the same time, I am conducting a comparative study of observations and simulations using direct observational diagnostics.
